Abstract
An apparatus and method for determining a valid user input in an electronic device is provided. The electronic device generally includes a touch unit included in a touch input circuit, wherein the touch unit corresponds to a touch area, a signal generator configured to transmit a signal to a first signal line and a second signal line by generating the signal, a signal measuring device configured to measure a part of a modified signal based on the transmitted signal, and a signal determiner configured to determine whether a user input is provided to the touch area based on the measured signal. The first signal line connects the signal generator and the touch unit, and the second signal line extends from the signal generator and is parallel with the first signal line.
